RAILWAY GATE. APPLICATION FILED APE. 9, 1907.

" 'a mus-snm 2.,

Be it knowmthat I, ALBERT SPIEs, a citizen of the United States of America, residinvI at Louisville, inithe county ot Jefferson and State of Kentucky, have invented certain -new and useful Improvements in Railway- Gates, of which the\following is a specification. l

lembodying the invention.

This invention relates to improvements in railway gates and is designed as an improvement on my March, 1906,- nunibered`814,330.

An object of this invention is to so improve the gate in the patent above referred to as to lighten it and reduce the cost of manufacture. By employiny this invention the applicant has found that the sections of the gate may be multiplied without making it unwield yet the said gate will possess practically t e same strength as it would possess if made entirely of metal.

In order to accomplish the result stated, the inventor has provided joints at the intersections of the partsof the gate and he has -provided novel pivotal connections whereby connected.

In order that the mode of use and utility the said sections of the gate are operatively l of the'invention may be appreciated, reference is made to my former patent, it being understood that the ends of the sections of t-he gate will be connected with the operating mechanism just as it is in the patent, this invent-ion relating more particularly to the construction of the gate proper.

W'ith the foregoing and other objects in view, the invention consists inthe details of construction and in the arrangement and combination of parts to he hereinafter more fully set forth and claimed.

In describing the inventionin detail, reference will be had to the accompanying drawings forming 4a part of this specification wherein like characters denote corresponding parts in the several views, in which Figure 1, is a view in elevation of a gate Fig. 2, is 'an end view of the gate in its contracted position.

ling em loyed in the invention. Fig. 8, is an enlarged vsection of the central coupling. Fig. 9, is an enlarged inside view of an outer section of an end coupling. Fig. 10, is an enlarged view of a face of an intermediate section of the end i coupling.

In the drawings A, B, denote the bars of the gate which are duplicated throughout.

the length of 4the gate and each bar A, has metallic lend caps I, and a'center colpling D. The bars A, are in pairs. The hars lie between pairs of `bars A, and each bar B, has I end caps b, and a coupling b.

Each coupling b, is

rovided with trunnions F, which enter bearings b, in the coupling D, and they `lay be secured therein in any desired manner, preferably by bolts G, run through the center thereof and secured by a nut g. Thecou lings D, have apertures d to receive bolts or rivets for attaching the coupling to' the bar. The end caps b are also provided with trunnions H, which have bearings in the end capsI, on the hars A, hence the bars A and Bare pivotally connected at their ends and at points intermediate thereof.

The end caps I, are secured to the bars A,

by rivets or other securing devices, which are. run through apertures i, and each end cap b, is secured to a bar B, by devices run through the a erture b3.

and at the ends are ful y shown in Fig. 2,

and in the sectional view, Fig. 4. The couphas an a erture in its center portion to receive the earings 5*, The wal ofthe couplings b', are provided with apertures b2, to receive fasteners 'for retaining the bar and coupling in assembled relation. As shown in the drawing, the bar A, is a continuous strip having end caps as heretofore described. fIhe har A, is shown in Fig. 6, as extending through the center cou ling.`

Should the wooden ars of this gate become broken or otherwise impaired, the said bars may be readily divested of metal fittings and the said fittings may be utilized-'in connection with perte-ct'- wooden bars, so that the cost of repairing is. minimized. The

metal parts of the gate are of such strength and durability as to withstand wear and hardship.

it will be observed that the inner ends of the portion be, are seated in the aperture of the couplings b, where they are secured in any manner. The intermediate section b2, may be a continuous strip having end caps or it may be formed of two strips having their ends seated in the couplings b. The outer sections A, extend from the. end caps to the intermediate coupling, but do not extend through the said coupling. This is Well shown in'Fig. 5.

What I claim is: 1. A coupling for/an expansille gate conirising a central hollow body, truiinions proleeting from said body, side bodies, and bearings carried bythe side bodies to engage the" trnnnions of the central body. i

2. A. coupling for an expansible gate coinprising a central hollow body closed at one end, trunnions projecting from -said body, side bodies, and bearings carried by the side oies to engage the trunnios of the central SYIn an expansible gate, the combination of a central bar, a coupling embracing said central bar intermediate its lengtlnsaid coupling being provided with trunnions, parallel side bars arranged one on either side of the central bar, a coupling carried by each of the side bars, bearings carried by the couplings of the side bars to engage the trunnion's of the cou ling of the central bar, and means for .pivotal y uniting the ends of the central bar means for pivotally uniting the ceiit-ral bar and the side bars centrally of their length, caps carried b v the erols of the central bar, trunnions on the caps, caps carried b`y the ends of the parallel side bars, bearings carried by the caps of the side bars to clivage the trunnions of the caps of the central ar, said side bars being suitably perforated to permit engagement of th-e bearings and the trnnnions ereinbefore referred to.

In testimony whereof, I aflix my signature in t'lie presence of two Witnesses.
